STOVE-POLISH.

SPECIFICATION forming part of Letters Patent No. 557,842, dated April 7,1896.

Application filed December 27, 1894:. Serial No- 533,049. (Nospecimens.)

To all whom, it may concern.-

Be it known that we, FREDRICK E. LOF- GREEN and WILLIAM H. WHIsLnR, ofMuscatine, in the county of Muscatine and State of Iowa, have inventedcertain new and useful Improvements in Stove-Polish; and we do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to certain improvements in stove'polishes.

The object of the invention is to provide an improved compound havingpowdered aluminium as a metallic basis and which is so combined withother ingredients as to constitute a practical and thoroughly operativestove-polish which will quickly dry and will not be affected by acontinuous high degree of heat.

The invention consists in forming a mixture of a certain proportion ofaluminium powder with rosin and a highly-volatile mineral oil in properproportions.

In carrying out our invention and preparing the improved stove-polishthe rosin is dissolved by a volatile mineral oil and the very fine purealuminium-metal powder is thoroughly mixed therein.

The compound is spread in a thin film on the stove, and the solventevaporates off, leaving a high polish of the natural color of the purealuminium metal, and which does not require rubbing to polish, and whichretains its color and polish, does not readily burn, peel, or rub off,but is most lasting and stands the high and continuous heat of thestove.

In making the compound usually one-half as much aluminium powder, byweight, is employed as rosin and benzene or gasolene and one'third asmuch rosin as benzene. Hence one formula of my compound could bealuminium powder, two ounces; rosin,0ne ounce; benzene or gasolene,three ounces.

By reason of the peculiar nature of this compound as an entirety itconstitutes a successful stove-polish that can be applied to the stovewhile hot and will dry immediately, or when applied to a cold surfacewill dry in two or three minutes and will not rub or burn off norblister.

The invention differs radically from and we make no claim' for compoundsused in stamping fabrics or for japanning various kinds of material andwhich are in no sense stove-polishes and are absolutely inoperative forsuch use.

IVhat we claim is The herein-described stove-polish formed of thefollowing ingredients mixed in about the proportion stated; viz. benzeneor gasolene one-half; powdered aluminium metal two-sixths; rosinone-sixth, substantially as described.

In testimony that we claim the foregoing as our own we affix oursignatures in presence of two witnesses.
